DEVICE FOR COUPLING ROPE.

SPECIFICATION forming part of Letters Patent No. 330,722, dated November 17, 1885.

Application filed August 27, 18x25. Serial No. 175,520. (No model.)

To a/ZZ whom, it may concern.'

Be it known that we, JAMns MILNE and JOSEPH J. MILNE, citizens ofthe United States of America, residing at Scotch Grove, in the county of Jones and State of Iowa, have invented certain new and useful Improvements in Devices for Coupling Rope; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates to an improved device for coupling or fastening rope, the object of the same being to provide a coupling or fastening which is specially adapted to be used with wire rope; and our convention consists in providing a disk having a grooved circumference, one side of said groove being provided with a notch through which one end of the rope may pass, said disk also being provided with means for attaching a chain or other connecting device thereto, and a hook which is located on the edge of the disk opposite the side which is provided with a notch, as will be hereinafter fully set forth, and specifically pointed out in the claims.

Our invention also consists in the construction and combination of the parts as shown, and pointed out in the claims.

In the accompanying drawings, which illustrate our invention, Figures l and 2 are side views of our improvement, and Figs. 3 and 4 are sectional views. A

A represents the disk, which is provided at its periphery with side fianges, a a, between which is formed a recess, the base of which is spiral, as shown in Fig. 3, the highest and lowest portions of said recess being adjacent to a notch, b, which is formed in one of the flanges a of the disk. Theflanges a a are braced to the central portions of the disk by convergent ribs c, and the central portion of the disk is provided with an irregularshaped opening, A. The disk A on the same side as the notched recess b has an upwardly-projecting portion, B, which is provided with a perforation, d, to which may be'attached a suitable chain or device for receiving a connection. The opposite flange is also provided with an extended portion, B, which may be bent inwardly, so as to form a hook, D, which will project over the recess or groove between the anges ce a. rIhe base ofthe notch b is rounded, so that the rope may project laterally therefrom, and when it is desired to secure the rope upon the fastening device the loose end is passed around the periphery of the disk between the side flanges, ct a, and under the hook D, the opposite end passing laterally out of the base of the notch b, as fully shown in Fig. 2. By this arrangement of the parts the greater the strain is upon the end x of the rope the tighter the same will become, as the portion of the rope which passes over opposite will force the same farther into the notch b and the groove between the side fianges, a et, so that it will be clamped more tightly therein as the pressure increases.

This device or fastening may be used in taking up the slackrof the rope, and may be attached thereto either at its ends or center; and it will be seen in the construction hereinbefore described ywe provide a fastening which will not slip, cut, or crush the rope, or in any way injure the same, and by means of this device the rope may readily be coupled or uncoupled.

It will be readily seen that the device herein described forms a convenient means for fastening a rope in posi-tion, in which case a chain, as shown, may be secured to an object or post, and the rope passed around the periphery of the disk as hereinbefore described.

If desirable, a piece of strap-iron, E, may be passed spirally around the circumference of the disk and attached thereto by rivets, so as to re-enforce the same. lWhen such construction is employed, the hook D, instead of being formed integrally with the disk, may be formed of the terminal portion of this strap.

We do not wish to confine ourselves to the exact construction or arrangement of the parts as herein shown and described, but reserve the right to modify our invention within the scope of our claims.

We claim- 1. In a fastening device for ropes, a disk having side flanges so as to provide a circur ferential recess, one of said flanges having a tangential recess through which the end of the rope may pass, substantiallyr as shown, and for the purpose set forth.

2. In aropefastening device, a diskhaving a circumferential recess or groove, a notch, b, formed in one of the flanges, and a hook formed on the opposite ange, substantially as shown.

3. In a rope-fastening device, a disk having a chain or connecting device attached thereto,

a circumferential recess with a spiral base,

said disk being provided at the beginning or commencement'of said spiral base with a tangential notch, b, substantially as shown, `and for the purpose set forth.

4. .A disk, A, havingside anges, a a, braces c, and a circumferential recess having a notch,

b, in one of the said flanges, the opposite zo flange being provided with a hook which overlaps the circumferential recess, and a fastening device located between the hook D and notch b, the parts being combined and'organized substantially as shown, and for the purpose set forth.

In testimony whereof we aix our signatures in presence of two Witnesses.
